FAN MECHANISM FOR HAMMOCKS.

SPECIFICATION forming part of Letters latent No. 643,107, dated F y 3, 1900- Application filed October 15,1898. Serial No. 693,650. (No model.) I

To all whom, it may concern:

Be it known that we, ENOOH B. BROWN and CARLTON W. BROWN, citizens of the United States,residing at Mystio,in the county of New London, State of Connecticut, have invented certain new and useful Improvements in Fan Mechanism for Hammocks, of which the following is a full, clear, and exact description.

This invention has for its immediate object the production of novel fan mechanism for antomatic use with ordinary hamm ocks,the combination of hammock, fan, and connecting mechanism being such that the swinging movement of the hammock will give motion to the fan and thus induce an artificial breeze. This desirable result we attain by means of very simple and inexpensive devices, as we shall explain. To assist in such explanation, we have provided the annexed sheet of drawings, in which 7 Figure 1 is a side elevation of a hammock properly supported and having connected therewith our newly-invented mechanism. Fig. 2 shows in elevation said hammock and mechanism as viewed from the left hand of Figs. 3 and 4 show modified forms of certain elements of our device.

Referring to the drawings, the letter a denotes a hammock hung in the usualmanner between posts I) and adapted to swing from its points of support the hooks b.

The reference-letter 0 denotes a rail or shaft located above hammock aand extending from one to the other of the posts I), the opposite ends of said rail being journaled in bearings 0', located near the upper ends of the posts (2.

Depending from rail 0 at points approximately equidistant from the central portion thereof are two arms (1, adapted to receive and support between them the fan proper of our device. Said fan consists of a rectangular frame e, having stretched thereon cloth or the like material e and having extending from each of the opposite shorter sides of the rectangular frame 6 a short journal 6 In order that the fan may hang normally in a vertical frame, but maybe free to swing as a pendulum when in service, we locate the journals c above the center of frame e,and we then support the said journals a loosely in bearings in the arms d. To thus receive the journals of the fan, the arms d are preferably provided with notched bearings cl, within which said journals are free to rock, as hereinafter explained, and in order that the location of said fan relatively to said hammock may be adjusted the arms (1 are provided with a series of the notched bearings (1', as shown.

Depending from rail 0, near one end thereof, is a short arm f, having an opening f therein, which said arm is adapted to coact with a lever g, hung on a stud b projecting from the adjacent post b at apoint somewhat above the hook I). The upper end of a lever g is provided with a right-angular extension g, which enters the opening f of armf, and the lower end of said lever g, as here shown, is bifurcated, as at g to straddle the strands of the hammock a near one end thereof. Any other suitable connection with the hammock'might, however, be provided.

It will now be readily seen by reference to Figs. 1 and 2 of the drawings that when hammock a is swung from its points of support (the hooks 1)) such motion imparts through lever g and arm f rocking motion to the rail 0 and the arms d, secured to said rail, said arms carrying the fan and the latter alternating with the ham mock in the direction of its movement.

In addition to the just-described swinging movement of the fan the rocking of the arms d, carrying said fan, causes the latter to oscillate as a pendulum, as will be readily understood by reference to Fig. 2, and thus a much stronger breeze is created than would be the case should said fan remain at all times in its normal vertical position or should the same be rigidly secured to the arms d.

The described movement of the fan, actuated by the swinging of the ham mock, imparts a breeze to the occupant thereof, and thus adds much to his comfort, the said breeze being both cooling and serving also to drive away insects, and such results are attained through the ordinary swinging of the hammock, no special exertion being neccessary, and said fan being adj ustably supported, as above explained, permits the adjustment thereof in order to accommodate the position assumed by the occupant of the hammock.

Our device may also be used as a sunshade, and when so employed the fan is adjusted to the proper point to screen the occupant of the hammock from the sun, said hammock remaining, of course, ina stationary position.

In Figs. 3 and 4 We have shown modifications in the manner of securing arms (1 andf to rail 0, consisting of screwing the same into said rail, and also a modification in the construction of the arms d, consisting in substituting for the notches d an opening (P, from which there lead a number of notches d to receive the journals 6.

Our device as a whole is of very inexpensive and simple construction, can be readily applied to ordinary hammocks, and adds much to the enjoyment and comfort of the user.
